ABSTRACT:
A multiple-layer wall is provided for a hollow body to sustain high thermal and mechanical loads and to afford adequate thermal insulation. The wall has, on the inside, a heat and/or wear resistant ceramic inner layer and, surrounding it, a preferably prestressed retaining layer of fiber reinforced plastic. An intermediate layer of a thermally insulating ceramic material can also be provided. The wall can also have a retaining layer of metal. At least the retaining layer is shrink-fitted. The retaining layer of metal and/or the intermediate layer moreover can be deposited by a sintering process. Prestressing is achieved also by the shrinkage resulting from the sintering process. As a result of prestressing, the inner layer, when under internal pressure, comes under substantially no circumferential tension or under circumferential compression only. The wall is used especially with precombustion chambers of Diesel engines or with cylinder barrels or internal combustion engines.
